the kingianum should get bright light but needs a cool dry rest. I mover mine outdoors as early in the spring as I can. It stays moist during growth. It stays out until right before the first frost and then comes in to a south facing "green house" window, over my kitchen sink, where it stays cool and dry until the spikes start breaking the sheaths in late winter. I then start watering them again. Only feed D. kingianum with a low nitrogen fertilizer or you will get keikis instead of flowers. If you should develop some keikis during the year, and some clones will, leave them on the plant until after they flower in late winter and then remove the keikis and pot them up for trading. ...this cultural info was taught to me by Dr. Wilford Neptune. He had won many awards for his kingianums.

I find that D. kingianum also does well in S/H culture.
